Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This signal generator consists of a Schmitt trigger and an integrator. The output of the Schmitt trigger part opamp (opAmp1) is a rectangular signal with the amplitude VAmp and the frequency f. The output of the integrator part opamp (opAmp2) is a triangular signal of also the amplitude Vamp and the frequency f.
